Specification of Letters Patent.

Patented Apr. 18, 1911.

Application filed October 21, 1910. Serial No. 588,329.

To alL whom it may concern:

Be it known that we, JOHN SELLERS BAN- onori` and MAURrrz C. INDAHL, of Philadelphia, in the county of Philadelphia andi State of Pennsylvania, have invented a certain new and useful Im rovement in Mai trix-Holders for 'Dypeasting Machines;

and we do hereby declare the following to erence marked thereon.

This invention relates to matrix holders for type casting machines, more especially sorts casting as distinguished from casting and dcomposing machines, and has for its principal object to furnish a fixture by means of which the matrices commonly employed in connection with the composing caster may be utilized in the sorts caster, of which latter an example is to be found in Reissue Patent No. 12,819, of June 23, 1908.

The commercial matrices for the composing-caster are in the form of parallelopiped blocks of metal grooved peripherally to receive the partitions of the cellular die-case in which they are mounted and provided at one end with a matrix cavity and at the opposite end with a centering cavity for the reception of the centering pin by means of which a selected matrix is finally centered and then clamped upon the open end of the in old with the matrix cavity in register therewith. The matrix blocks while rectangular in crosssection vary in dimensions according to the number of cells they occupy in the die-case, as is illustrated in application Serial No. 500,557, led June 7, 1909. The sorts caster matrices on the other hand are flat plates with the matrix'cavity sunk in one face thereof, and to accommodate the same the machine is equipped with a special holder or die-case containing lthe centering cavity and matrix sup ortin and clamping devices, as illustrated) in atent Reissue 12,819 and Patent 904,510, of November 24, 1908.

The present holder is designed as a substitute for those heretofore supplied to the sorts- 'caster and lto accommodate 'any of the several forms of-matrices pertaining to the composing caster,`to"xthe 'end that the last named variety o`f vmatrices' may be 'rendered available in the sorts caster, and the final centering' be performed by the direct application of the centering pin to the matrix, as in the composing caster, rather than indirectly through the die case or holder as in the sorts caster. By this means the capacity g of the sorts-caster is greatly enlarged in that its product is not restricted by the number and variety of flat sorts matrices available for the purpose but is extended to include the larger number and variety of faces pertaining especially t'o' the composing caster.

With these ends in view the present invention consists in the novel construction, arrangement and combination of parts hereinafter fully described` and pointed out in the annexed claims.

In the accompanying drawings illustrating a preferred form of embodiment of the inrention-Figure 1 is a top plan view, Fig. 2 is a longitudinal section on line :zi-,

of Fig. 1. Fig. 3 is a transverse section on line y-y. of Fig. 1, and Fig. 4 is a longitu-` dinal section on line z-z, Fig. 5 is a perspective view of a one unit composition matrix. Fig. 6 is a similar view ofa two unit matrix for a vertical extended face. Fig. 7 is a similar view of two unit matrix for lateral extended face. Fig. 8 is a similar'view of a form unit matrix. Fig. 9 is afperspective view of one retainer and Fig. 10 1s a similar view of the other retainer.

Corresponding numerals designate like parts in the several views. i

Commercial cellular matrices for the composing caster are of uniform length (height) and rectangular in cross section; but they vary in lateral dimensions in multiples of the unit which is arbitrarily established at two tenths of an inch. Thus the single'unit matrix of Fig. 5 is square in cross-section; the two unit matrices'of Fi 6 and 7 twice the section of the single unit; and the four unit matrix. Fig. 8, is a square with sides vtwice the dimensions of the single unit. The two unit matrices represented in Figs. 6 and 7 diti'er in this that the one is extended column wise and the other set wise of the face,

ioo

the direction of the 4extension .being in'dicated by wider sections 1 of the peripheral grooves forming the suspension shoulders for the matrices.v

The problem presented is to supply a fixture adapted for use upon the sorts caster 'one and competent to hold any one of these different forms of matrices in proper relation to the centerin -pen and mold so that they may be utilized the-fein for the production of sorts or display type, :1s-distinguished from composed matter, the latter requiring "t l iees-together.lvith seleetive centerin and mold dimensionin mechanisms. This problem has been so ved in the manner about to be described.

The substantially flat frame 2 of the holder or die-case corresponds both in form and dimensions, save as to the inner or central section, with those heretofore employed in both the composingr and sorts casters, being thus adapted for application to the standard machines both for .positioning and reciprocating the matrix relatively to the mold. Within the space bounded by the side bars and ends of frame 2 the latter is provided with inwardly projecting flanges or plates 4 of less thickness than said sidebars and .ends,and designed to aiiord supports for the detachable gaging members or blocks 5, -6, by means of which adjacent sides of the matrices a-re positioned laterally of the centering point as determined by the centering pin and mold, and restrained from longitudinal displacement. Blocks 5 and 6. are each formed or provided with a 'longitudinal riborotfsetportion 7, the latterprojecting through; a' slot. or opening between. adjacent 4flanges-4, said slots preferably extending at right angles and intersecting at or ,near -the center of the frame. Each block is detachably'at-tached to webs 4 as by screw 8, the adjacent corners ofthe bases of said blocks being cut away,'as at 9, to permit the proximate ends of the ribs--7to'be maintai-ned in close juxtaposition. As thus arranged the .inner lface of the'blocksare disposed in parallel planes intersect-ing at right angles and eaeh block is furnished with a rib 10 adapted to enter the peripheral groove upon one side of the matrix.' The ribs 10 of the two blocks 5, 6, although of the. same Width stand in different planes, the upper edge of that in block 6 being .the higher to form ythe support for the shoulder of the Wider groove l of the matrix, soxthat both ribs will be engaged when a matrix is ins erted. The proximate gaging faces of blocks 5, 6,'form a fixed angular seat for the reception of the two surfaces ofthe matrix by Vwhich its matrix cavity is justified, at the sametime aiording suspension shoulders fpr preventing lon tudmal displacement while permitting limited independent movement ,of a matrix held in juxtaposition to said seat-1w; A

The holder is ,completed by. the'itaddition f 'of two removable, retainers 11, .12,each op..

posite and in parallel with one ,of;said gaging -suI Jjagses .and ldistant therefrom a V.predetermined ',degree correspondingj ywith `the` unit of the matrix or a multiple thereof, as will presently appear, said retainers serving to prevent lateral displacement of the matrix when engaged with `its seat on blocks 5 6.

ralitly of holders for locating and maintainingit in any one of several positions relatively to the oppsed gaging surface, `and in the present instance said holders' are in the form of .parallel grooves13 in the upper -75 face of each block 5, 6. The grooves 13' of each block are spaced to correspond with the matrix unit and the inner one is located one unit removed from the gaging surface of the other block, Retainers 11, 12, are preferably in the form of straight blades, and when occupying their respect-ive holders or grooves 13 their inner ends intersect and are locked together against lateral displacement by means of notches 15, each of said blades b eing provided with a notch alining with each of the receiving grooves 13 of the associated block, said notches being formed in the under edge of one blade and Athe upper edgeof the other blade, to Ithe end that when inter- 90 locked' the two blades shall lie in the same plane. Each retainer 11, 12 is pivotally attached lto its block 5 or .6 by a pin 14 extending transversely of grooves 13 at the rear ends thereof and the block is cut away or recessed intermediate the grooves as at 14* to permit the retainer- Lto be shifted from one groove to the .other without-the necessity'of withdrawing pin 14, thus preventing accidental displacement or loss of ,the retainer. The upper'blade yor retainer 11' is also pro.- vided with a lateral extension 16 containing two perforations 17 for the passage of the centering pin and forming a protect-mgeover for the centering end of the matrix, .to prevent mutilation of the latter should thelv cenf tering pin be advanced or lowered when the holder is out of position, that is, dis laced to such an extent that the point of t e pin would not fairly enter the centering. cavity of the matrix at the time in the holder.

The adaptability of the holder to receive the various forms and dimensions of VIna-trices illustrated will be readily perceived. When a one unit matrix, Fig. 5, .to be 1.15 employed, retainers 11', `12, occupy .the grooves 13 nearest the fixedgaging surfaces. By elevating the upper or both retainers .the gaging surfaces are uncovered sutiiciently to permit the matrix to 'be seated, after which 1.20 the retainers are seated in grooves "13 ,and the matrix will be locked against displacement.

If the matrix desired is of the two unit variety, F igs; 6 and 7, :that one of .the re- 1.25

tainers 11, 12, corresponding with the ex.- tension is withdrawn from the inner and deposited inthe outer groove 13. Thus if the matrix of Fi 6 is to lhe used, retainer 11 is elevated an shifted upon pin 14 until 1,30

it registers'with the groove 13 most remote from block 6, and, if the matrix of Fig. 7 s

. called-for', the position of 'retainer-12 is lf -wit-h-respeertfrblocir- 5. To accommodate the four unit matrix oi Fig. 9 it is only required that both retainers be translated from the innermtqnthev should the capacity of the matrix recess or cell our fold.

'In practice the centering cavity of the multiple unit matrices is eccentrically 1o. cated s o as to occupy. the same position relatively to the two gaging sides of the matrix as does the centerin cavity of the one'unit matrix (seeapplication Serial No. 500,557)

'and it is to accommodatel this feature that the protecting-plate of retainer 11 is provide with two centering pin perforations .spaced oneunit apart, so that when said retainer is conned in the near groove 13'representing a single unit in that direction, one

of said perforations will be in register with the matrix cell and when said .retainer is shifted to the next or distant groove 13 for a two or four unit matrix the companion perforation will be brought into register with the axis of said cell. als is obvious-the fixed gaging surfaces or angular-'seat for 'the matrix might be contained in an integral. block attached to the holder frame or be-made integral therewith, but 'the construction illustrated is preferred Las reatly -facilitating.manufacture and inially supported to swing tia positioning.

5T eretainers'll, 12, are preferably pivotupward upon what sthe u per'surfaceo the holder when in the mac ine so that gravity will suice to maintain them" in operative position within Ythe dimensioning rooves after the matrix `has been inserted 1n the holder, but other means may,' if desired,A be employed for removably-seeuring the retainers inthe selected groove or holder. u
